September 2025 update

Sorry for this long time of silence. A lot of new information was gathered over this past month, in addition to the “Dove of Peace” series described in the previous page. The data are summarized hereunder, thanks to Kenneth Sequeira (Dubai), Ali Allawati (Oman), Adam Paish (UK), Enzo Cafaro (Italy), Dominique Josse (France), Sim Tng Kwang (Singapore), Mohamed Achour Ali Ahmed (Algeria), and Marci Jarvis (USA).

The official day of issue of the Oman stamp related to the Arab Postal Day from August 3, 2025, initially announced as being released on August 10, 2025 for this country, has to be corrected to August 3, 2025, according to FDC images provided by Ali Allawati.

The Oman stamps from the Oman Iran issue initially scheduled to be released on May 27, 2025, became available only on August 26, 2025 (date shown on the Oman FDC cover). However, information from Iran is still missing and we do not know if it will become a real joint issue, despite the clear indication on the stamp itself.

The Maldives-Singapore joint issue which design was revealed on June 30, 2025, was finally released on September 5, 2025. This issue includes two stamps featuring fishes, turtle, corals, the Lazarus Island (Singapore) and Hulhudhoo (Maldives), which were also included in a souvenir sheet (Singapore). Good quality images and final product description from the Maldives are still missing.

Singapore was involved a second time this month, on September 19, 2025, to celebrate the 60th anniversary of Thailand-Singapore diplomatic relations. As previously, Singapore issued also both stamps in a form of a souvenir sheet. The Thai stamps has been printed in se-tenant checkerboard-formatted sheets of ten stamps.

On September 16, 2025, the 640 years of the crowning of Sigmund of Luxembourg in Hungary was supposed to be celebrated by Luxembourg and Slovakia with a common stamp which design was released earlier this year by the Slovak Post. It happened that this issue disappeared from both postal administration philatelic programs. Explanations are needed here.

The Mythical heroes crypto-stamps series was issued on September 18, 2025 (see detailed description under previous page). The final illustrations given below show small changes compared to initial illustrations provided earlier (e.g., new denomination for Luxembourg). The series includes Austria (2 units, Zeus and Hera, 2×150,000), Belgium (Athena, 20,000), Luxembourg (Artemis, 15,000), Netherlands (Hermes, 25,000) and Portugal (Poseidon, 25,000). The digital twins are stored in the blockchain in five different colors. The likelihood of getting a particular color depends on the color: for Luxembourg stamps, there are 150 red, 1,005 yellow, 1,995 blue, 4,005 green and 7,845 black stamps; for the other countries the exact number of colored subtypes has not been published but the figures remain probably close to the same ratio, i.e., 1% (red), 6.7% (yellow), 13.3% (blue), 26.7% (green) and 52.3% (black). The digital twin of the crypto stamp is randomly generated. By scanning the QR code on the stamp with a smartphone, one will find out which color is linked to the crypto stamp.

As an example, the Luxembourg stamp digital twins in the blockchain look as follow:

On September 25, 2025, the Embassy of the Republic of Peru in Kuwait hosted an event to present a commemorative postage stamp marking the 50th anniversary of diplomatic relations between Kuwait and Peru. The postage stamps are featuring Kuwait’s Red Palace and Peru’s Real Felipe Fortress. Unfortunately, to our knowledge, this Peruvian stamp will remain unilateral.

The Oman-Russia joint issue, originally scheduled for April 22, 2025, postponed to September 26, 2025 (Oman source), then, a few weeks ago to October 15, is now scheduled for November 14, 2025. The date of October 15, 2025 remains unchanged for the issue of the joint stamps involving Laos and Russia and the first illustration of the Russian stamps became available recently.

Arab Post Day update and more to come

Both previous blog pages triggered attention from collectors and resulted in additional information that help complete the catalogue:

Regarding the Arab Postal Day issue [T20250803], two additional countries have to be added to the already reported list (Algeria, Iraq, Tunisia, and the United Arab Emirates) namely, Egypt and Oman which issued their stamps respectively on August 3, 2025 and August 10, 2025 (Information provided by Mohamed Achour Ali Ahmed, Algeria and Ali Allawati, Oman).

The 80th Arab League anniversary issue from March 22, 2025 [T20250322] was also completed by two stamps issued in miniature sheets of 3 pairs from the United Arab Emirates. These stamps were issued on August 18, 2025 (Information provided by Kenneth Sequeira, Singapore).

The previous blog page was also missing the image of the Russian stamp jointly issued with North Korea on August 15, 2025. Illustration was provided by Kenneth Sequeira, Singapore, confirming the twin character.

I also made a comment earlier that embroided stamps are never used postally. Henri Aronis (France) provided a proof that this can happen with a Swiss stamp (year 2000), although not part of a joint issue. As expected, the thickness of the ‘stamp’ makes cancellation illegible. This cover was sent from Switzerland to Niger. Thanks Henri.

Jaap Sarelse (the Netherlands) reacted on the comments provided earlier about the July 5, 2025 Cape Verde – Portugal joint issue and at the same time provided information about Angola, a third country joining this issue, with the following:

The text suggests that it is a joint issue in which only Cape Verde and Portugal are involved. However, Angola is also involved with an identical stamp. Not to commemorate Angolan independence, but purely focused on the independence of Cape Verde. Some evidence:

  • In the leaflet of the Portuguese Post (6 pages) the text on page 5, 7th and 8th line from the bottom reads: ‘To help consolidate the historic memory of the founding of the Republic of Cabo Verde, a joint stamp issue is being released by Angola, Cabo Verde and Portugal’.
  • On page 5, one can find the stamps of Angola on the top row. Cabo Verde is also mentioned on this stamp at the bottom right.
  • Finally, only Cabo Verde is mentioned in the logo on page 1. I suspect that in the context of ’50 anos Independência Nacional’ Angola will get its own joint issue and that the name Angola will then adorn below the stars in the logo

Thanks, Jaap for this complement. Catalogue will be updated. Here are the additional illustrations (Angola stamp illustrations provided by Kenneth Sequeira):

Additional information relative to issues to come include the following:

  • The Oman – Russia originally scheduled for April 22, 2025, is now postponed to September 26, 2025 (Oman source) or October 15, 2025 (Russian source), not clear at this stage. It will show maps and honour Omani explorer Ahmed bin Majid and the Russian traveler Afanasy Nikitin
  • Kenneth Sequeira reported also two modifications in the Russian philatelic programme for 2025: a) the RCC stamps will be issued on August 23, 2025, but over the past years these stamps involving all CIS countries were not anymore considered as joint and there is no hint that this will change this year; b) the anniversary of the liberation of Korea will be celebrated by overprinting the August 15, 2025 joint issue with North Korea. These stamps will be issued on September 2, 2025
  • On October 7, 2025, the France – Japan is also confirmed. Japan stamp designs became available (information provided by Dominique Josse, France)

  • On August 15, 2025, Argentina issued a stamp to celebrate 60 years of immigration from Korea. No stamps related to the same topic was seen so far in the South Korea philatelic program. This issue may remain unilateral (information provided by Enzo Cafaro, Italy)

  • Our friend Luis Alejandro Malanco Reyes (Mexico) is working on a Mexican stamp catalogue (which of course includes also joint issues involving Mexico) and brought on line the first part of his work (years 2001-2025) with free access: Catálogo Filatélico México . Congratulations Luis and keep doing the good job.

Finally, some information about the next joint crypto-stamps issue (not recommanded to include in the joint issue collection as explained earlier): This will be the fourth crypto joint issue after the 2022 Austria-Netherlands (Ox), 2023 Austria-Luxembourg-Netherlands (Lion) and 2024 Austria-Belgium-Luxembourg-Netherlands (dragon) issues. The theme for this fourth issue is the Greek world of the gods. Five countries will participate and they made the following choice: Portugal – Poseidon, Austria – Zeus and Hera (2 stamps), Belgium – Athena, Luxembourg – Artemis and the Netherlands – Hermes.

Jaap Sarelse has succesfully created joint stamp covers with the previous crypto stamps and will try again this year with the six stamps. He provided the picture of the copy from year 2024. Such documents are close to unique.

The catalogue was update with all above new data. See updated Vol 1, Vol 15 and Vol 16
